Designer/Educator

Electronics hobbyist, engineer, physicist. I have lived and worked in quite a few places around the world. Overall, I believe in a united, peaceful and caring humanity since we have one home that connects all of us. Planet Earth.

  • Software PLL syncs to line using moving-average filter
  • Maybe you should write to Mike and ask him to arrange a tutorial of with design examples for your filter design tools on the EDN site? I have perused the brochure and it seems like a useful tool - a little too vague at this point. No demos, except by arrangement....

  • One wire brings power & data to LCD module
  • Today there are so many low-cost, large-pin count MCUs out there today that one is confounded by the choice. In the old days this DI would have brought a blast of fresh air.

  • Flyback switcher works down to 1.1V, flashes HBLEDs
  • LoL! That's easier said than done. I live in RSA that's considered more advanced than other African countries. Even here (new) specialist components can only be imported. The Customs setup here seems over-zealous to the extent that importing even by "mail box" is subject to heavy import duties. I had a nasty surprise recently when I bought from eBay a component from HK for US$ 9 and I ended up paying US$27. BTW it took 42 days to get here by HK Mail. Some of these things HAVE to be experienced to be believed.

  • Monolithic PWM generator runs fast, minimizes silicon
  • Permit me to moan a bit, thanks. This great article shows that design ideas can hit the big time, with commercial ramifications. I am just a tad concerned that Europractice Multi-Project Wafer service caters only for European universities and institutions, and others like MOSIS, CMP and WaferCatalyst may have country restrictions as well. DIs up to the present haven't really cared about the country of origin - with the exception of the recent LPC1000 inductive sensing contest (sigh!). I hope DIs will always remain open.

  • IoT entering peak of inflated expectations
  • Actually, after posting my earlier comment I googled "The Uncanny Valley" and I notice that the Hype Cycle and the Uncanny Valley plots look remarkably similar in shape http://en.wikipedia.org/wiki/Uncanny_valley . It must all have to do with how humans think and behave.

  • IoT entering peak of inflated expectations
  • A very nice read, I learnt a lot. I couldn't help noticing that on the Hype Cycle the Plateau of Productivity never came close to the Peak of "Inflated" Expectations ever again. I wonder who is responsible for the inflation of expectations: is it media, is it the companies themselves, the public? This study kind of reminds me of the Uncanny Valley in robotics.

  • Sine Tips
  • I couldn't stop laughing. Good old John Dunn! I guess if it works for you, why change it?
